Have a check engine light on our 2008 cayenne turbo
Was intermittent (sometimes came on and then cleared itself) but now on all the time. Engine seems a little sluggish and down on power.
Code is P0016 which relates to cam/crank position correlation issue. I've replaced the cam hall sensor on bank 1 (left side of v8 as viewed from front of car looking into engine bay) and cleared the code and performance seems better but after a 5 mile drive and a check with code reader I've noticed that the same code is pending and I assume the check light will return.
Any ideas of other possible causes?
I've read perhaps a failing variable timing solenoid or one that's dirty or partially blocked could cause this? I think the car is just about due a service.
TIA
